data envelopment analysis (dea) is a non-parametric method for assessing relative efficiency of decision-making units (dmus). every single decision-maker with the use of inputs produces outputs. these decision-making units will be defined by the production possibility set. resource allocation to dmus is one of the concerns of managers since managers can employ the results of this process to all...

subject of palestine is neither a local nor an arabic issue but it is an islamic subject and all muslims in the world assume themselves responsible for it. disasters in palestine have caused pain in heart of all muslims throughout the world. this is a land that has been usurped from its owners and became a homeland for those ones who have come there from different points of the world and unlike...

This paper proposes a new resource allocation model which is based on data envelopment analysis (DEA) and concerns systems with several homogeneous units operating under supervision of a central unit. The previous studies in DEA literature deal with reallocating/allocating organizational resource to improve performance or maximize the total amount of outputs produced by individual units. In tho...

It is crucial for effective water resource management in a watershed that the relationship between land use changes and baseflow. This study quantifies the influence of land use changes on the baseflow dynamics using a hydrological model and partial least-squares (PLS) regression in the Upper Du Watershed (8961 km2), China. Our study suggests that forest can be a major factor with a negative im...

Computer modeling is gaining popularity in the study of systems whose underlying processes are difficult to observe and measure directly, or their controlled experimentation is not an option. Since real-world phenomena, for instance psychological or ecological, are often hugely complicated, and the models trying to capture their essence relatively complex, validation of the models and selection...
